Hi, this all seems fairly new kit - perhaps around 2019? E.g. MBO Z390 AORUS PRO WIFI-CF (U3E1)
You've referred to low transfer rate regarding one particular HDD - I don't know how many or what other disks you may have- if you have more, please confirm whether you see the same issue with those.
Low transfer rates + 100% disk use have been reported a number of times here over some years. Usually this ends up being a driver issue, but can be hard to resolve.
1. Please download and run Hard Disk Sentinel (trial) - portable version also available- SSDs too. Analyses connectivity as well as reporting health right on its GUI.
Post a screenshot of that for each disk in your system.
2. History (so often omitted by posters):
- when did this start?
- was this disk originally ok?
- what was the last major build of Win 10 you were running when it was ok?
- did this problem start after a Windows feature update (upgrade)?
3. Have you tried reseating the drive/cable or changing the cable?
4. An analytical approach would be to use the Windows Performance Analyser (WPA) free from MS - technical, graphical representation of how time is used by processes, drivers etc.
5. Please feel free to look for similar threads here as examples by searching for
